WATER CLOSET Filed Jan. 21, 193] 3 Sheets-Sheet 3 Zi-denial? l Patented Nov. 1o, 1931 UNITED stares PATENT OFFCE i JOHN C. DUNER, OF CHICAGO, ILLINOIS WATER c'LosEcr i Application filed January 21, 1931. Serial No. 510,079.

This invention relates to water closets provided foruse in railway cars and like locations and while it will hereinafter be described as embodied in a. water closet of the general character of that shown in the copending applications of .iohn C. Duner for United States Letters Patent, Serial Nos. 375,242 and 375,243, iii-ed July 1, 1929, it

, will be readily apparent that from certain quently occurring with considerable velocity and producing a blast directed upwardly through the toilet or closet. In the co-pending applications above referred to, a draft member is disclosed for sealing the closet outlet as an incident to the flushing of the toilet.

This draft member' )referabl and in accordn o 5 li l l ance with the disclosure of said pending apphcations, moves into a sealing or closing position during the initial opening movement of the dump pan and prior to the breaking tion contemplates the provision of an operof the water seal.

The invention has for its principal object improvement in the dump pan and draft,

member operating` mechanism. The invenating mechanism of the character described of simple construction, easy operation, and the quick and early closing of the draft meinber at each flushing of the toilet.

' The invention has for a further important object the provision of means for tightly pressing the draft member to sealing position and to hold the same closed with a toggle lock. i

Another important object of the invention is the provision of a spring pressed mechanism, the parts of which may be so constructed Vand arranged as to permit lthedumping of thedump pan or its movement to an open Iposition without requiring aV corresponding closing movement of the draft member, this feature permitting flushing through the toilet for cleaning purposes in the railway yards.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, talren in connection with the accompanying drawings, discloses a preferred em- .Y

bodiment thereof.

Referring to the drawings:

Figure 1 is a side elevation of a closet embodying the present invention;

Fig. 2 is a front view thereof, parts being .broken away and shown in section to disclose certain features of construction;

Figs. 3 and l are partial views similar to Fig. 1, showing positions the parts assume inthe operation of the closet;

Fig. 5 is an enlarged axial section of the spring housing and associated parts; y

Fig. 6 is a detailed sectional view showing the pin and slot connection between the operating arm and the pivot shaft ofthe dump pan, and y f Fig. 7 is a section taken at right angles to the section of Fig. 6.

The water closet shown on as exemplifying the embodiment of the inf vention at present preferred, comprises a metal stand or support 11, a ceramic bowl 12 supportedby the stand and above the bowl outlet 13, va flush valve mechanism 14 a dump pan 15, and a draft member 16.

The dump pan is pivotally supported in the base'for downward swinging, its pivot shaft 17 extending through` and being mounted inside bearings 18. At one side, i. e. the .side shown in Figs. 1, 3, and l1,'the'shaft 17 is embraced by a sleeve 19 in which'is provided a slot 21. A pin 22 is liXed in the shaft and arranged for movementinthe slot 21. An arm 23 is formed integral with the sleeve 19 and is provided at its free end with a pin 24 arranged in a slot 25 inthe lower the drawings end of a depending link 26 pivotally con- Y nected at 27 atits top with a hand lever 28 adapted to be lifted to flush the toilet by Vdumping ofthe dump pan `and opening of 'at theirkupper ends to stud or pivot shafts y 82 arranged inside bearings 33.

At one side an arm 34e is 'Xed on the outer end of the stub shaft 32 and is connected by a link 35 to one arm 36 of a two-armed lever, the other arm 37 of which is connected by link 38 to an end 39 of a reciprocating rod 41 mounted within a sleeve 42 pivoted at 43 on the stand 11. A spring 44 is arranged within the sleeve and bears at its inner end against an enlarged head 45 on the rod 41 and at the other end against a cap 46 arranged about the rod and secured to the open end of the sleeve. The arm 23 is extended beyond its connection with the link 26 into pivotal engagement at 47 with the fulcrum of the lever formed of the two arms 36 and 37.

A weight 48 is arranged uponY an extension 49 of the right hand arm 31 (viewing Fig. 2). A second counter balancing weight 51 is provided upon the right hand end of the dump pan pivot shaft 17. The arrangement of the weight 48 and the arms 34 and 31 is such that Vwhen the sealing member is in sealing position, i. e. closing the outlet 53 of the closet, the weight 48 has passed vertically beyond the laxis 32 of the movement of the draft member to aid in locking the draft member in closed position.

When the hand'lever 28 is raised, the arm 23 of the sleeve 19 moves to bring the pin 22 into engagement with` the end of the slot 21 and swing thedump pan downwardly. The pin and slot V connection just described permit preliminary motion of the draft member to the sealing position shown in Fig. 3 before the dump pan commences its downward swing. Thereafter continued upward movement of the hand lever 28 causes the link 26 to pull up the arm 23, swinging the dump pan down and lifting the weight 51 as may be observed'in Fig. 4. During the initial movement, i. e. during the movement while the sealing member is closed, little compression of the spring 44 is accomplished. As the spring is compressed, resultingpressure is exerted to hold the sealing member tightly to its seat.

If desired, the dump pan may be dumped without corresponding closing movement of the draft member by lifting up on the weight 51 to merely swing down the dump pan.

It is thought that the invention and many of itsattendant advantages will be understood from the foregoing description, and it will-be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A water closet, comprising a closet bowl supported above its outlet, a dump pan positioned beneath said bowl and adapted to swing from a'sealing position downwardly to a dumping position, a draft member located beneath said dump pan and arrangeable in a sealing position as an incident to the opening movement of said dump pan, and a dump supper .ed above its outlet, a dump pan positioned beneath said bowl and adapted tok swing from a sealin g position downwardly to a dumping position, a draft member located beneath said dump pan and arrangeable in a sealing position as an incident to the opening movement of said dump pan, a dump pan and draft member operating mechanism, and a sprintf,` pressing said draft member to its seat.

3.
